Capping Compound

CA-0100

Test Mark Ultra-Strength Capping Compound is used to cap the ends of concrete test cylinders so compression force will be evenly distributed to the cylinder during testing. The compound comes in the form of ultra-thin flakes for better heat transfer, faster melting, and easy, dust-free pouring. Compression strength is 8,000 psi by the 2" cube test method in 2 hours, 260°- 290° F melting range.
